The number of historic buildings which ________ has reached a surprising figure that we must be aware of.
A.has been pulled down B.had been pulled down
C.is being pulled down D.have been pulled down
D
选D 考查时态和主谓一致。句意:我们必须意识到,已被拆毁的历史建筑的数量惊人。主语部分含有一个which引导的定语从句,先行词是buildings,因此从句中的谓语应该用复数形式。再根据句意可知,此处用现在完成时,表示“已经被拆毁的”。
